More Data Archiving

I’m actually looking into the WDCP updates page more regularly now to see if any new information has been archived. Five more Jacoby data sets have been archived in the past week: one from the Yukon, 4 from Mongolia. There are still far more that have not been archived than have been archived, but that makes about 30 data sets so far this year.

There was one other curiosity in the recent archiving. In our NAS Panel presentation, we cited a study by Biondi et al [1999] from Idaho, which was a millennial length tree ring study, pointing out that it claimed "low frequency" similarity to the bristlecones prior to the mid-19th century (as Mann did with the Jacoby treeline reconstruction), but that the 20th century results were quite different in the various cases.

Biondi is one of the NAS panelists. While we talked about the need for archiving data, we did not mention to the NAS panel that Biondi et al had not archived the Idaho data set used in the reconstruction.
